Cil

Having described my invention, what I claim as new and wish to secure by Letters Patent is:

l. An envelope comprising a body having integrally formed lower and side flaps adhesively united to form a packet, contents therein, and an upper flap adapted to form a closure element for said pocket, one of said ilaps terminating in a centrally elongated member in the form of a loop with its end adhesively secured to the inner face of the front wall of the envelope, said upper flap being free of said elongated member and overlying the same whereby said elongated member retains the contents of the envelope when the upper flap is opened.

2. An envelope comprising a body having integrally formed lower and side iiaps adhesively united to form a packet, contents therein, and an upper flap adapted tor form a closure element for said pocket, one of said side flaps terminating in a centrally elongated member in the form of a loop with its end adhesively secured to the inner face of the front wall of the envelope, said upper flap being free of said elongated member and overlying the same whereby said elongated member retains the contents of the envelope when the upper ilap is opened.

3. An envelope comprising a body having integrally formed lower and side flaps adhesively united to form a packet, contents therein, and an upper ap adapted to form a. closure element for said pocket, one of said naps terminating in a centrally elongated strap provided with central elongated opening leaving narrow sheerable retaining strips, said strap being in a form of a loop with its end adhesively secured to the inner face of the front wall of the envelope, said upper flap being free of said elongated strap and overlying the same whereby said elongated strap retains the contents of the envelope when the upper ap is opened.
